Non-Rectangular Display Device GIP Circuit Crosstalk Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-rectangular display devices face issues with crosstalk and image quality deterioration due to intersecting gate and data lines, as well as the risk of short-circuiting from static electricity, which are not effectively addressed in conventional rectangular display technologies.
Innovation Solution
The implementation of a display device with a non-rectangular shape featuring gate-in-panel (GIP) circuits and GIP lines in the non-display region, which are configured to manage gate and data signals independently, preventing intersections and static electricity-induced shorts, and ensuring consistent data line lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gate lines and data lines are arranged orthogonally in a non-rectangular display region, then the display device can achieve various non-rectangular shapes, but gate lines and data lines may intersect in the non-display region causing crosstalk
Solution Approach 1:
The patent divides the display device into distinct display and non-display regions with different line arrangement strategies. In the non-display region, data lines are segmented to extend parallel to gate lines rather than intersecting them, while in the display region, orthogonal arrangement is maintained for pixel addressing. This segmentation resolves the contradiction by allowing shape flexibility in the display region while preventing crosstalk in the non-display region.
Solution Approach 2:
The patent applies different arrangement qualities to different regions: in the display region, gate and data lines are arranged orthogonally to enable pixel addressing, while in the non-display region, data lines are arranged parallel to gate lines to prevent crosstalk. This local differentiation of line arrangement quality allows the device to achieve non-rectangular shapes without suffering from crosstalk issues.
2Ease of operation
If data lines are extended to cover the entire display region, then all pixels can be addressed, but the length of each data line varies causing image quality deterioration
Solution Approach 1:
The patent introduces a second directional component for data lines in the non-display region. Instead of extending data lines only in one direction (causing length variation), the lines are configured to extend in a first direction in the display region and in a second direction in the non-display region. This dimensional change allows all pixels to be addressed while equalizing data line lengths, thereby maintaining image quality uniformity.
3Device complexity
If gate lines and data lines intersect in the non-display region, then the wiring can be simplified, but static electricity may cause short-circuiting during manufacturing
Solution Approach 1:
The patent extracts the data lines from the orthogonal arrangement pattern used in the display region and repositions them to run parallel to gate lines in the non-display region. This extraction of data lines from the intersecting pattern eliminates the short-circuit risk during manufacturing while maintaining simplified wiring through the systematic parallel arrangement in the non-display region.

AI summary
A display device includes a display unit having a non-rectangular shape. A plurality of data lines and a plurality of gate lines intersect each other in the display unit. A plurality of gate in panel (GIP) circuits are arranged in a non-display region of the display device that has a shape corresponding to the shape of the display unit, and each of the GIP circuits is connected to a respective gate line. A plurality of GIP lines are connected to the GIP circuits. The GIP lines transmit respective gate control signals to the GIP circuits, and the GIP circuits apply gate signals to the gate lines based on the gate control signals. Source lines are arranged in the non-display region, and transmit respective data signals to the plurality of data lines. At least one data line is arranged parallel to the gate lines in the non-display region.
